Answer:

the sequence begins as {4, 7, ... }

Step-by-step explanation:

a(n) = 3n + 1

The first term is a(1) = 3(1) + 1 = 4, and

the second term is a(s) = 3(2) + 1 = 7

So the sequence begins as {4, 7, ... }

Gemiola [76]

Answer: 72

We can use ratios

117 inches / 13 inches = 9

The corn cast shadow is 9 times bigger than the example we are given.

9 * 8 = <u><em>72</em></u>

The graph of f ′ (x), the derivative of f of x, is continuous for all x and consists of five line segments as shown below. Given

Rom4ik [11]

$f'(x)\ge0$ for all $x$ in [-3, 0], so $f(x)$ is non-decreasing over this interval, and in particular we know right away that its minimum value must occur at $x=-3$ .

From the plot, it's clear that on [-3, 0] we have $f'(x)=-x$ . So

$f(x)=\displaystyle\int(-x)\,\mathrm dx=-\dfrac{x^2}2+C$

for some constant $C$ . Given that $f(0)=7$ , we find that

$7=-\dfrac{0^2}2+C\implies C=7$

so that on [-3, 0] we have

$f(x)=-\dfrac{x^2}2+7$

and

$f(-3)=\dfrac52=2.5$

I need help with these 4 questions on my math homework! I have some examples with it but I still don't know how to do them... (S

lesya [120]

Step-by-step explanation:

For equation N°2

$-x-3 = 0\\$

Solving algebraically:

$-x + x -3 = x$ (Sum x on both sides of the equation)

$-3 = x\\$

Resolving graphically:

x = -2 --------- - (- 2) -3 = -1 pto (-2, -1)

x = -4 ---------- - (- 4) -3 = 1 pt (-4.1)

x = -3 --------- - (- 3) -3 = 0 pt (-3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution

For equation N° 4

$9x +3 = 0\\$

Solving algebraically:

$9x+3 -3 = -3$ (Sum -3 on both sides of the equation)

$9x =-3$

$\frac{9x}{9}=\frac{-3}{9}$ (divided by 9 on both sides of the equation)

$x =\frac{-3}{9}$ (simplifies the fraction)

$x =\frac{-1}{3}$

Resolving graphically:

x = 1 --------- 9 (1) +3 = 12 pt (1.12)

x = -1 --------- 9 (-1) +3 = -6 pto (-1, -6)

x = -1 / 3 -------- 9 (-1/3) +3 = 1 pt (-1 / 3.0) Solution

The graphic is shown in the attached image. The red dot in the graph represents the solution

For equation N°. 6.

$4x + 11 = 4x-24\\$

Solving algebraically:

$4x -4x +11 = 4x -4x-24$ (Sum -4x on both sides of the equation)

$11 = -24$ The equation is not met, the x are eliminated, therefore, it has solution

For equation N°. 8

$-6x +3 = -6x + 5\\$

Solving algebraically:

$-6x + 6x +3 = -6x + 6x +5$ (Sum 6x on both sides of the equation)

$3 = 5$ The x are eliminated, 3 is not equal to 5, the equality is not met. The equation has no solution.
